I need 13.8 volts dc for a 50 watt ham radio and maybe a 5 watt cp
radio. What would i need, 20 amps?
What amperage would you have? What would you want for them?

All you need is about 6 amps (55 watts/14 volts=3.9, 55/12=4.6) , so a
10 amp unit would be lots.

And if you want to have true Emergency Preparedness, for the same
price as a heavy power supply go get yourself a 90AH or 105AH Deep
Cycle RV battery and a well filtered small (2-amp) float charger.

You can run as big a transmitter you want as long as it's in normal
short bursts. The charger has all night to bring the battery back up
between uses.

(But make sure to put the battery in a well-ventilated protected
area, not inside the house. Acid, Hydrogen... You can run #2 cable
50 feet out to the garage.)
